Type the correct answer in the box. Jay, Kip, and Tia are each measuring the concentration of a solution. They are doing experim
Kryger [21]

Answer:

  • <em>The measurements taken by </em><em><u>Jay</u></em><em> are least likely to contain random errors.</em>

Explanation:

All experimental measures are subject to errors.

Even when the colorimeter is properly calibrated and correctly used, there are random errors.

Random errors are are due to fortuitous factors, such as minor oversight by the observer or small changes of the conditions under which the measurements are made.

You can minimize the random errors by increasing the number of measurements, because the random errors tend to happen in any direction; some measures will be greater and other will be less than the true value.

Chance will make that errors in on direction cancel with errors in the opposed direction, making the average the best measure.

Thus, <em>Jay</em>, by <em>repeating the experiment five times and taking the average measurement</em>, is making that<em> his measurements are</em> <em>least likely to contain random errors.</em>

natka813 [3]

Answer: well there is a lot of examples that can be used but i feel like a good answer will be a flower peddle once broken its still a peddle but its either larger or smaller than what it originated. another example can be a tree. you can have many trees that are huge in size or you can have small ones. once snapped in half it will still be a tree but the size of the tree will not remane the same but it will still be a tree through and through
